VIBRATORY ACTUATOR.

Specification of Letters Patent.

Patented Jan. 1,1918.

Original applicationfiled August 1 2, 1913, Serial no. 7 4,342. Divided and this application filed March 30, 1917. Seria1 No.158,747.

T 0 all whom it may concern:

Be it known that I, EDWIN H. Mnssrrnn, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Vibratory Actuators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to vibratory means for producing a rotative movement and has for one of its objects to provide an oscillatory or reciprocatory actuator or escapement mechanism that shall be adapted to effect a step by step rotative movement of the driven member.

In order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification and then point out the novel features thereof in appended claims.

This is a divisional application of application Serial No. 7 84,342 filed August 12, 1913, in which the subject matter of this application was originally disclosed.

Hy present invention is concerned with the escapement mechanism per se, which is clearly adapted for general use, apart from the electro-responsive actuator which is shown and described in my co-pending application Serial No. 856,917, filed August 15, 1914.

Referring to the drawings:

Figure 1 is an elevation of a vibratory mechanism embodying my invention.

A part of the same mechanism is shown in its opposite position in Fig. 2.

The device illustrated comprises an oscillatory member pivotally mounted at 10 and comprising an arm 11 to which is secured a circuit controller 12 and an armature 13, and an arm 14, which is fashioned to produce a double pawl structure comprising fingers 15 and 16.

The armature 13 is located between a pair of stationary magnets 18 and 19 having core members 20 and 21.

25 is a star wheel mounted on a shaft 26 to which any suitable driven member may be secured such as for example, a set of counters for an integrating meter (not shown).

Each of the fingers .15 and 16 has an end 22 and a shoulder 23 which are so positioned and proportioned relative to each other and to the center of the shaft 26 as to engage the teeth 27 of the star wheel 25. 7

[Assuming that the magnet 19 is first energized so that it attracts the armature 13 to theposition shown in Fig. 1, the shoulder 23 'of'finger 16 will engage one of the teeth 27 moving the star wheel and its connected parts, until the end '22 of the saniefinger the star wheel moving itin the same direc-' 7 tion of rotation as indicated by arrow 30, until a tooth comes into engagement with the shoulder 23 of the finger 15. The teeth 27 are arranged and proportioned to co operate with the double pawl in the manner described. The finger and shoulders of the pawl are so shaped and arranged that their driving engagement with the teeth of the star wheel is nearly a straight push with a minimum slip, and the stopping engagement is direct and positive.

The circuit may be controlled in any suit able manner such as, for example, the bulb or tube 12 which is substantially horizontal when the arm 11 is midway between the ends of its swing, and is provided near its respective ends with sets of contacts 31 and 32 and contains a small quantity of mercury or other conducting fluid.

It is evident that when the arm is oscillated into the position shown in Fig. 1, the circuit previously established is broken at the contacts 31 which are disconnected while the mercury or other conducting fluid in the tube interconnects the terminals 32 so that a circuit may be completed therethrough. When the arm is oscillated into the position shown in Fig. 2, the circuit is broken at the contacts 31 and the circuit may be again.

completed through the contacts 31.

By completing the circuits through the contacts 31 and 32 to alternately energize the magnets 19 and 18, the bell crank lever will be oscillated so as to produce a step by step movement of the star wheel.

mechanism per 86, Which may be used independently of the actuating and control mechanism.

Furthermore, it is evident that the actuator 14 may be reciprocated in a straight, line instead of oscillated and it is in fact intended to represent a movable actuator of particularly simple and desirable form.

WV hat I claim is:

1. An escapement mechanism comprising a pivoted star Wheel, and a lever in the same plane as that of the Wheel, pivoted at one side of said Wheel, said lever having two rigid fingers extending on opposite sides of the Wheel, each of said fingers being fashioned to form an integral actuating abutment and a stop abutment cooperating with the actuating abutment on its finger.

2. Anescapement mechanism comprising a pivoted star Wheel, and a lever having tWo rigid fingers each fashioned to provide a rigid actuating abutment and a rigid stop abutment cooperating With the actuating abutment on the same finger.

3. An escapement mechanism comprising a pivoted star Wheel and a movable member having two rigid fingers each fashioned to provide a rigid actuating abutment and a rigid stop abutment cooperating with the actuating abutment on the same finger.

In Witness whereof, I have hereunto set my hand this 29th day of March, 1917.
